Mono(p-tolyl)platinum(II) and bis(p-tolyl)platinum(II) complexes of diethylsulfide as reagents for organoplatinum synthesis. Structures of [Pt(p-Tol)2(μ-SEt2)]2 and PtCl(p-Tol)(bpy) (bpy=2,2′-bipyridine)

The complex trans-PtCl(p-Tol)(SEt2)2 is obtained from the reaction of [Pt(p-Tol)2(SEt2)]2 with PtCl2(SEt2)2 and SEt2 in mole ratio 1:2:2. The mono(p-tolyl)platinum(II) and bis(p-tolyl)platinum(II) complexes of diethylsulfide react with 2,2′-bipyridine to form the complexes PtX(p-Tol)(bpy) (X=p-Tol, Cl) and are useful reagents for organoplatinum chemistry. X-ray crystal structures are presented for square planar PtCl(p-Tol)(bpy) and the centrosymmetric dimer [Pt(p-Tol)2(μ-SEt2)]2.
